What Pink Tail Chalceus look like

Chalceus macrolepidotus, commonly known as the Pink Tail Chalceus, exhibits a sleek, laterally compressed body that can reach a maximum adult size of approximately 10 inches (25 cm). The species is characterized by its strikingly large, reflective scales that shimmer in light, contributing to its visual appeal. The most distinctive feature is its caudal fin, which displays a vibrant pink to rosy-red coloration, contrasting beautifully with its predominantly silver body. Sexual dimorphism is subtle, with males typically exhibiting slightly more pronounced coloration in the fins during breeding periods. The species possesses a well-developed lateral line system, aiding in its navigation through the water column. Additionally, its dentition consists of small, sharp teeth adapted for grasping a variety of food items, while its adipose fin is present, contributing to its streamlined shape, allowing for powerful swimming capabilities.

Behavior & temperament

The Pink Tail Chalceus is a highly active and social fish, often found in small to medium-sized schools, which enhances its safety from predators. It primarily inhabits the mid to upper water column, displaying pelagic tendencies. This species is known for its dynamic swimming behavior, often darting through the water with agility. Breeding behavior involves egg scattering, where females release eggs in open water, allowing for external fertilization. The temperament of Chalceus macrolepidotus is generally peaceful, though it can exhibit territoriality during breeding periods, particularly among males competing for mates.

Diet & feeding

In the wild, the Pink Tail Chalceus is an omnivore, feeding on a varied diet that includes insects, small crustaceans, and plant matter. In captivity, it requires a balanced diet consisting of high-quality flake food, supplemented with live or frozen foods such as brine shrimp and bloodworms to ensure optimal health and coloration.

Behind the name

Chalceus (from Greek 'chalkeus', meaning 'copper') refers to the fish's metallic sheen, while macrolepidotus (from Greek 'macro' meaning 'large' and 'lepidotus' meaning 'scaled') describes its notably large scales.
